Heat-Shrink Tube Kit Norimpex TERMO-TUBE-PACK/1.5-13/BL — assorted diameters 1.5–13 mm

Norimpex TERMO-TUBE-PACK/1.5-13/BL is a set of heat-shrink tubes in assorted diameters from 1.5 mm to 13 mm designed for insulating and protecting electrical joints, cables and connectors. The kit supplies thermally shrinkable sleeving that secures connections against moisture ingress, provides mechanical strain relief and increases abrasion resistance. It is intended for repair, wiring, harness assembly and routine electrical maintenance where matched tube diameters are needed for reliable insulation and neat installation.

Advantages

The assortment contains multiple diameters to suit a range of conductor sizes and connector profiles, enabling precision fit and consistent shrink performance. Heat-shrink material offers good dimensional recovery when heated, forming a tight protective layer that resists wear and environmental exposure. The kit simplifies inventory and minimizes the need to buy individual tubes, making it practical for workshops, service engineers and DIY electrical work.

Suitable for

• Insulating soldered or crimped wire joints
• Protecting cable terminations and connector ends
• Strain relief on cable transition points
• Repairing damaged cable insulation
• Harnessing and bundling wires in control panels and vehicles

Key specifications

• Diameter range: assorted nominal diameters from 1.5 mm up to 13 mm before shrinkage
• Shrink ratio: standard thermal shrink performance suitable for forming a tight seal over connectors and conductors
• Material: heat-shrinkable polymer providing electrical insulation and abrasion resistance
• Color: black sleeves for general-purpose use and UV resistance
• Typical applications: electrical insulation, strain relief and environmental protection of joints

How to use

Select a tube diameter slightly larger than the target component before heating to ensure good fit. Slide the chosen sleeve over the joint or cable area, then apply heat evenly using a heat gun or controlled flame at a safe distance until the tube contracts and conforms to the underlying shape. Allow the sleeve to cool so it sets in place. For moisture sealing, ensure the sleeve fully covers the exposed area and that shrinkage produces a snug contact with the substrate.

Usage recommendations

Use a temperature-controlled heat gun for even shrinkage and to avoid overheating nearby components. For applications requiring enhanced sealing, select sleeves with adhesive lining or pair with appropriate sealants. Store the kit in a dry place away from direct sunlight to preserve material flexibility and shrink properties.
